Characterization and catalytic investigation of NO+CO reaction on perovskites of the general formula LaxM1−xFeO3 (M=Sr and/or Ce) prepared via a reverse micelles microemulsion route

An experimental and kinetic study of toluene oxidation over LaMn1−x B x O3 and La0.8A0.2Mn0.3B0.7O3 (A=Sr, Ce and B=Cu, Fe) nano-perovskite catalysts

“…With introduction of Sr and Ce to the structure of perovskite catalysts, their specific surface areas were decreased. The results were in agreement with those of other researchers [26][27][28].…”

Effect of different synthetic routes on the structural, morphological and magnetic properties of Ce doped LaFeO3 nanoparticles

“…There exist reports on doping of LaFeO 3 with Ce, which mainly highlights the improvement of catalytic and sensing properties of these materials [20][21][22]. Similarly, Giannakas et al [23] have reported that Ce doping in LaFeO 3 resulted to high catalytic activity toward the NO + CO reaction. However, in these reports, no detailed investigations were made on optical and magnetic behavior of Ce doped LaFeO 3 nanoparticles.…”

Modified LaCoO3 nano-perovskite catalysts for the environmental application of automotive CO oxidation

“…These methods include pyrolysis, co-precipitation, citrate complexation, spray-drying, freeze-drying, microemulsion sol-gel process, etc. [10][11][12][13]. Among those, the benchmark methods are coprecipitation and citrate methods [7,10].…”

“…Giannakas and his co-workers [12] prepared four different perovskite-type solids with nominal composition LaFeO 3 , La 0.85 Sr 0.15 FeO 3 , La 0.8 Sr 0.1 Ce 0.1 FeO 3 , and La 0.8 Ce 0.2 FeO 3 via a reverse micelles microemulsion route. The aim of their work was to investigate the effect of doping with Sr and Ce on the structural properties, surface area, and catalytic properties of final solids in comparison with un-doped reference solid LaFeO 3 .…”
